The invention provides a spectrum sensing system and method based on a fusion attention mechanism, and the method comprises the steps: a sample generation module is used for generating a covariance signal and an IQ time sequence signal, and achieving the comprehensive analysis of a time domain and a frequency domain of the signal; the feature extraction module is used for capturing key information in a covariance signal and an IQ signal, and carrying out dimensionality reduction and denoising operation at the same time, so as to reduce the dimensionality of data and remove unnecessary noise, and improve the calculation efficiency and the perception capability; the feature fusion module realizes multi-scale fusion of data features by introducing a multivariate attention mechanism, and ensures full utilization of information and feature integrity; meanwhile, the module dynamically learns and adjusts weights among different features, and the calculation efficiency is improved; and the discrimination module conve
